Grails searchable plugin with hasMany - grails

Question

I am using grails searchable plugin to search my domain classes. However, I cannot yet search by my hasMany (skills and interests) fields even though they are of the simple type String. This is my domain class:
class EmpactUser {
static searchable = [except: ['dateCreated','password','enabled','accountExpired','accountLocked','passwordExpired']]
String username
String password
boolean enabled = true
boolean accountExpired
boolean accountLocked
boolean passwordExpired
String email
String firstName
String lastName
String address
String phoneNumber
String description
byte[] avatar
byte[] resume
Date dateCreated
static hasMany = [
skills : String,
interests : String, // each user has the ability to list many skills and interests so that they can be matched with a project.
]
static constraints = {
username blank: false, unique: true
password blank: false
email email: true, blank: false
firstName blank: false
lastName blank: false
description nullable: true
address nullable: true
avatar nullable: true, maxSize: 1024 * 1024 * 10
resume nullable: true, maxSize: 1024 * 1024 * 10
phoneNumber nullable: true, matches: "/[(][+]d{3}[)]d+/", maxSize: 30
}
}
This is the code I am using to search:
def empactUserList = EmpactUser.search(
searchQuery,
[reload: false, result: "every", defaultOperator: "or"])
Am I missing something?
Thanks,
Alan.

Searchable has trouble recognising hasMany relations with Strings. A workaround is to create a new domain object which "belongs to" the parent object, and make a transient variable in the parent class. The following code works as an alternate to the example given in documentation.
class Article {
static searchable = {
root true
keywords (component:true)
}
static transients = ['keywords']
Set<ArticleKeyword> getKeywords() {
ArticleKeyword.findAllByArticle(this) as Set
}
}
class ArticleKeyword {
static searchable = { root false}
static constraints = {
}
String text
static belongsTo = [article:Article]
static mapping = {
text type: 'text'
}
}
